. IMPROVEMENT IN WHIFFLETREES AND TRACES.

lSpecification forming part of Letters Patent No. 134,227, dated December 24, 1872.l

Y which the bllowing is a specification:

Figure 1 represents a top view of my invention. Fig. 2 is a detail longitudinal section on the line o c, Fig. 1. Fig. 3 is a transverse vsection on the line k 7c, Fig. l.

Similar letters of reference indicate corresponding parts.

This invention has for its object to avoid injury to field-plants by the projecting ends of single-trees or whifietrees of agricultural machines. The invention consists in so constructing the whiffletrees or single-trees that the traces when attached thereto will be flush with their ends. At present many plants are injured by the projecting ends of the whit-lietrees of cultivators or other agricultural niachines, and large sums of money in consequence annually lost to the country.

In the drawing, the letter A represents a single or whietree of suitable size held in place on the machine by suitable means. B is the trace attached to one end of the tree A.

' To the end of the trace is riveted the ange a of a short tube, C, the ange being concave v ping the tube C over the latter, and then fastening the tube by a suitable key, b, as shown. This trace-connection need only be at that end of the whiftietree which will sweep past the rows ot' plants. It will leave the traceilush with the end of the tree and leave no projection on the latter to tear down or injure the plants. For double teams the two outer ends ofthe whiffletrce may be thus protected by the traces, while the inner ends may have suitable other fastenin gs for single teams, but that end may be so protected which will pass near the plants. The other end may have a suitable trace-connection.

The drawing represents a tube, D, as applied to the other end of the tree A, said tube having a projecting hook, d, to which the chain-trace E is secured. By having the tube E' the sin gle-tree is prepared for either kind of fastening at either end, and the leather trace need only be used on one side, the other side having the more economical chain E.

Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- The tube C having Han ge a concave on outer face, and receiving a leather trace, B, as and for purpose described.
